Data tracking method for data storage device, involves detecting off-track error of probe with respect to data storage medium, and adjusting scanning position of probe with respect to medium to compensate for error

摘要

The method involves oscillating a probe on a data storage medium based on a low-frequency signal generated by a controller, where the probe has a cantilever to support a tip (11a). An off-track error of the probe is detected with respect to the medium using a signal synchronized with a data position pattern of the medium. A scanning position of the probe is adjusted with respect to the medium to compensate for off-track error. An independent claim is also included for a data storage device comprising a data storage medium.
